Work completed

Project description updated to include #PowerTree #ActuatorDriver #Sequencing #Filtering
System Architecture property with mermaid flowchart added
Generic decoupling capacitors for U2/U3/U4 and bulk capacitors C1–C6 on +35V_IN

TVS diode (printhead ESD protection) on V35_HV
All nets (+35V_IN, V35_HV, V5, V3P3, V1P8A) wired end-to-end, including PGOOD connections to U6
PGND, AGND, and DGND tied at a single star-tie node
“Sequencing and Isolation” property added with detailed startup order and LVDS isolation paths

What’s left

Review schematic with ERC/DRC and adjust connections, component values, and ratings as needed (this step can’t be automated)

Success criteria

Rails (+35V_IN, V35_HV, V5, V3P3, V1P8A) all implemented with filters and sense circuits: ✅
Power-tree and actuator driver wiring, EMI/inrush, ESD, and PGOOD sequencing: ✅
Star-tie ground isolation and LVDS paths annotated: ✅
ERC/DRC review pending: ⚠️

Next step Run an ERC/DRC check, resolve any warnings or errors, then proceed to prepare the PCB layout.

Description

Power Tree and Actuator Driver with Robust Filtering, Current Sensing, PGOOD Sequencing, and Star-Tie Grounding

Properties

Sequenci…solation

Power-up rail order: +35V_IN -> EMI_IN -> V5 -> V3P3 -> V1P8A. Sequencer U6 monitors: V5 (U3:PG), V3P3 (planned PG from downstream load), V1P8A (U4:OUT via sense/flag). Ground domains: PGND (power/switching returns: U3:PGND, Q2 source network, R5/R11 low sides), AGND (quiet analog reference: U3:AGND, D3:C TVS return, U4:GND, sense amplifier/monitor references), DGND (digital/logic returns, reserved for LVDS and control logic if added). Star-tie implementation: AGND, PGND, and any future DGND are shorted only at the single net/interface represented by net GND (components: GND portals and U3 AGND - U4 GND star symbol), forming the sole copper junction on the PCB. LVDS isolation paths (conceptual documentation): LVDS link from upstream controller into this board shall cross isolation at the PGND/AGND star-tie; any LVDS receiver or digital isolator is referenced to DGND, with its return bonded to the star node so that high di/dt currents on PGND (Q2 switching, V35_HV current sense R5, snubbers R6/R9/C10/C11) do not flow in the LVDS or analog ground references. Documented rails and monitoring points: +35V_IN (TP1), V5 (TP2), V3P3 (TP3), V1P8A (TP4), V35_HV/EMI_IN node (TP5) plus per-rail shunt low-side test points TP6–TP9 for current-sense verification. This property summarizes startup rail sequence, ground-domain star-tie, and intended LVDS isolation boundary; schematic portals and GND symbols on Pages 2 and 3 are annotated accordingly.
